Pkviz is a tool for plotting and cycling through and animating a series of network packets captured by tcpdump. What makes it unique is that the packets’ structure is visualized, not any labels and not time itself. Pkviz takes each byte in a packet and plots it out end-to-end, left-to-right, from the first byte to the last. How high the dot gets plotted depends on the value of the byte: bytes with a value of 0 are at the bottom and those which are 255 (0xff) – the maximum value of a byte – get plotted at the top. This might not be interesting for one packet, but that changes when you start looking at thousands of packets. Pkviz can cycle through thousands of packets in the set so you can see what happened on the wire.

NoSpex is a Python scripted realtime graphing library designed to be easily employed by security consultants and reverse engineers for teasing apart and depicting the relationships between processes in a system under analysis. It is realtime in the sense that the graph is continuously rendered and animated as new relationships are introduced. It is easily employed in the sense that all the bookkeeping is done by the Python module and exposed using a simple thread-safe API. NoSpex relies on the SDL graphic library for a frame buffer and Cairo for rendering to the frame buffer. This combination produces a fast and visually elegant graph that should be portable wherever SDL and Cairo can be found.

CanvasJS is an HTML5 charting and graphing library built on JavaScript and the HTML5 Canvas element. It runs across devices and performs 10x better than SVG and Flash-based charts. It is fully interactive and can render 100,000 data points in just over 100 milliseconds.

jmxtrans is effectively the missing connector between JMX and whatever logging or graphing package that you can dream up. jmxtrans is very powerful tool that reads JSON configuration files specifying servers/ports and JMX domains/attributes and then outputs the data in whatever format you want via special "Writer" objects that you can code up yourself. It does this with a very efficient engine design that will scale to querying literally thousands of machines. The core engine is pretty solid and writers are included for cacti/rrdtool, graphite, and stdout.

SysopView shows information in a visually attractive way, like computers in movies do. The idea is that it can show information relevant to system administrators non-comprehensible for non-technical personnel, while still looking attractive even if you don't know what is shown. The current version can show nagios status data, webcam streams (mjpeg, jpeg, and video4Linux), and VNC, has a built-in terminal emulator in which regular text applications can be run, can sniff the network (including remotely) and dissect streams and show pictures which are sniffed, can show external bitmaps (from, for example, mrtg and rrdtool), and can scroll text (currently showing output of rssfeeds).

CSVSee graphs data from CSV files, especially those containing timestamps. You can graph all columns, or specific columns matching regular expressions. Graphs can be displayed in an interactive viewer, or saved to a .png or .svg file. Tools are also provided to generate CSV files by string-matching in multiple timestamped text files, and for creating CSV reports of Grinder load test logs.

Instavue extracts the Instaviz diagrams from the user's iPhone or iPod
Touch backups. The user can then choose to print the diagrams or export
them to any of these vector and bitmap formats: BMP, EPS, GIF, Graphviz,
JPEG, PNG, PostScript, SVG, TIFF, Visio VDX, or VML. Mac users can also
export to these additional formats: JPEG2000, OpenEXR, Photoshop, PDF,
Quickdraw, Silicon Graphics or TGA. Windows users can also export to the
EMF (Enhanced Metafile) format.

aerotools-ng provides a C interface for accessing the Aquaero5 USB device by Aqua Computer. It consists of a set of functions for data access and conversion, and a commandline tool using these functions as an example implementation. It also includes utilities for exporting sensor data to SNMP to be used by NMS and other monitoring/graphing tools.
